Compact, wideband antenna system

Attorney, Agent or Firm: Burke; William J.

A compact, wideband antenna system is provided by an open-sleeve, meander dual zigzag monopole consisting of a driven element configured from two symmetrically-oriented meander wires fed from a common feed point and one or two closely-spaced parasitic elements (open sleeves), also configured from two meander wires and shorted to ground plane. The meander monopole has a low silhouette and provides approximately 50% reduction in height as compared to a conventional monopole. By varying the size, geometry, and location of the open sleeves, antennas are synthesized to achieve specific frequency response characteristics. Measurements have demonstrated that the meander monopole is capable of providing the desired radiation pattern characteristics over a 3:1 frequency band.

DETAILED DESCRIPTION A compact, wideband antenna system is provided by a meander zigzag monopole antenna configured from one or more meander wires fed from a common feed point.
One or more open sleeves configured in a similar dual meander fashion are also provided to extend the antenna bandwidth.
